I found several posts about that trailing garbage.
If you extract pet with same command...you get it also. It means that there is some file which tar does not understand...but it does not mean that it wont be extracted.

l2ulinux,
I have just sent rcrsn51 a message regarding the source code and patches necessary to compile your driver ...
but before we do this, we definitely need to know the PCI device ID of your ethernet hardware.
So, as rcrsn51 asked in the second post, we need you to report the output of this command, please -

Update - I just saw your other post in the "Three-Headed Dog" thread, and your ethernet apparently works OK in Slacko!?
Three-Headed Dog and Slacko share the same kernel (and thus same drivers) so it's very strange that your ethernet is not working in 3-HD.

Also we shouldn't assume that the compatible driver is necessarily atl1e. It might be atl1c.
You mentioned that your ethernet device works with Saluki, Wary, Racy, Slacko, Dpup and Upup ... but unfortunately you didn't tell us which driver was being used. (It's listed in the Netork Wizard).

I suggest you do a fresh boot to the 3-HD CD, avoiding the pupsave file by specifying "pfix=ram" at the boot prompt, then run the Network Wizard and check if the atl1e driver (or atl1c driver) has automatically loaded and created a network interface.
If not, check for the presence of the drivers with these commands -
